This paper addresses the concern over the sustainability of Indonesia as a nation, based on the unifying ideology of Pancasila. Specifically, the paper is concerned with the views and conduct of the Indonesian populace regarding the country's multifaceted diversity, as well as their perspective on the national ideology of Pancasila.  Today, while some small groups consider Pancasila as an irrelevant national ideology, the majority of Indonesian people firmly believe that Pancasila has effectively served as a unifying force in the country. This is particularly evident when comparing Indonesia to other Muslim countries worldwide, which often grapple with disharmony, conflicts, civil wars, and even fragmentation. Their insights on the interplay between Pancasila and Islam have been a source of inspiration for the younger generation. Their contributions have played a significant role in establishing Pancasila as an ideology and a common platform, particularly in the face of attempts to undermine its principles. Even in the present day, their ideas continue to serve as a cohesive framework that unifies the diverse Indonesian population.
